ZFS ghost files on 11.3-STABLE

[Gareth de Vaux]

Hi all, I deleted a file (rm filter) by mistake instead of its backup 'filter~',
however it seems a remnant of a much older version of the file (given by its
date and content) is half hanging around?

$ ls -l filter 
ls: filter: No such file or directory

$ ls -l filter*
-rw-r--r--  1 lordcow  lordcow  18179 Mar 28  2019 filter 
-rw-------  1 lordcow  lordcow  19092 Nov 20 23:36 filter~

$ stat filter
stat: filter: stat: No such file or directory

$ stat filter*
1525321853 1911959 -rw-r--r-- 1 lordcow lordcow 4294967295 18179 "Mar 28 17:07:34 2019" "Mar 28 17:08:07 2019" "Mar 28 17:08:07 2019" "Mar 28 17:07:34 2019" 18432 24 0x800 filter 
1525321853 833819 -rw------- 1 lordcow lordcow 4294967295 19092 "Aug 10 22:31:53 2016" "Nov 20 23:36:40 2019" "Nov 24 23:08:13 2019" "Nov 20 23:36:40 2019" 19456 24 0x800 filter~

$ cat filter 
cat: filter: No such file or directory

$ cat filter*
(cats both files)

A zpool scrub returns no errors

I haven't tried to overwrite the file yet incase anyone wants some output.
